Atomizer construction



Patented Sept. 4, 1934 UNITED .STATES ATOMIZER CONSTRUCTION Louis V. Aronson, Newark, N. J., assigner to Art 4 Claims.

My invention relates to atomizers and has particular reference to novel arrangements of some parts of the atomizing mechanism. y

My invention relates toA novel features of atom- J' izer construction rendering the, same simpler, more eiicient, more, readily manufactured and more readily repaired, when necessary, than are prior art atomizing devices.

Further objects, advantages and characteristics of my invention will become apparent from the following detailed description taken in connection with the accompanying drawing.

My invention resides in the atomizer construction, arrangement of parts and combination of elements of the character hereinafter described and claimed. l

For an understanding of my invention and for an illustration o f one of the many forms thereof, reference is to be had to the accompanying drawing, in which:

Figure 1 is a vertical, sectional view, partly in elevation, of an atomizer constructed in accordance with my invention;

` Fig. 2 is an elevational view of the atomizer shown in Fig. 1 but with some of the parts in diiferent positions;

Fig.y 3 is a plan view, partly broken away, of the atomizer shown in Fig. 1; f

Fig. 4 is an enlarged, transverse, vertical sectional View, partly in elevation, and is taken on the line 4-4 of Fig. 1, looking in the direction of the arrows; and

Fig. 5 is a fragmentary perspective view of one end of a plunger rod and the spring associated therewith.

Referring to the drawing, C represents any suitable casing, container' or receptacle adapted to be supported on any suitable surface or to be carried about in a garment pocket, a hand bag ce the like. In the example shown, the casing C comprises a top wall land a bottom wail 2, said walls being joined by side wall structure 3 of anysuitable conguration.

Adjacent one side of the aforesaid casing, the top wall 1 is provided with aperforation receiving a rod 4 for reciprocatory'movement, said rod 4 carrying a suitable knob 5 at its upper end. The rod 4, at4 the end thereof removed from the knob .5, carries suitable piston structure and, therefore, preferably comprises va stem 4a of ref 'duced diameter externally threaded and receiving a first disk 6, a second disk or washer '1 and a third disk 8, all of the disks being held in assembled, relation on vthe stem 4a by a nut 9 threaded to the latter.

(ol. 29e-ss) flexible so that the outer section thereof forms a circular ange 7a when forced into vthe pump cylinder 10 winch is disposed interiorly of the casing C.

In accordance with the form of'my invention herein disclosed, but not necessarily, the pump cylinder 10 is so secured interiorly of the casing C that the upper end thereof forms a sealed joint with respect to the top casing wall while the lower end of said cylinder 10 extends, in sealed relation, throughv a suitable perforation formed in the bottom casing wall 2, said cylinder 10 being interiorly threaded to receive the externally threaded shank of a headed plug or cap 11.

The rod 4 is suitably biased in an upward direction, Figs. 1 and 2, and, for this purpose, there i75 may be utilized a helical spring 12, the lower end of which seats upon the upper face of cap 11 and the upper end of which is disposed around the nut 9 and seats against the disk 8. In accordance with a feature of my invention, the upper 'end of 80 spring 12 is of such diameter that it snugly fits` within the circular flange '7a' of disk '7 and applies pressure to said flange 7a Yto force the latter against the interior surface of pump cylinder 10.

In this manner, during the pumping action, passage or leakage of air between the aforesaid ange 'la and the pump cylinder 10 is greatly impeded. This action of the upper end of spring 10 is most marked on the down stroke of the rod 4, this beingdesirable because air is pumped on such stroke of the rod 4.

The vmechanism hereinb'efore described forms an air pump utilizable for intermittently producing streams of air to effect the atomizing action.

For the passage of such air, a pipe or conduit 13 95 is connected to the pump cylinder `10 at or immediately adjacent the lower end thereof, said conduit 13 extending through thev casing C at one side of said pump cylinder 10, and then through the top casing wall 1 where it terminates in a nozzle 13a angularly related with respect to a nozzle 14a of a pipe or conduit 14 extending downwardly through said top casing wall 1 and terminating interiorly of casing C atone side of the pump cylinder 10.`

A collar or ferruie 15 may be disposed on and secured to the upper surface of the top casingwall 1 and around the conduit 14 to more effectually retain said conduit 14 in the upright position illus, trated. If desired, the top casing wall 1 may which the aforesaid conduit 13 extends. Likewise,

if. desired, the abutment 1a may comprise a passage lb opening into the casing C at one side of the pump cylinder 10.

A member 16 disposed above the top casing wall 1 is supported for pivotal movement in any desired manner.' As herein illustrated and for this purpose, said top casing Wall 1 comprises or has a pair of spaced ears 17 upstanding therefrom and having a .pin or member 18 extending therethrough for pivotally supporting the aforesaid member 16.

The member 16, preferably, is cap-shaped or shaped somewhat as an inverted receptacle. Disposed therewithin and suitably secured thereto is a pad or member 18 of suitable flexible, resilient material, as softrubber, cork or the like, which is adapted to close the upper end of the conduit 14 and the upper endpf the passage 1b. For thus securing the member 18 interiorly of the member 16, there may be utilized a member 19 of deformable sheet material which, as shown, in Fig. 4, is soldered or therwise suitably secured to the lower surface of t \e top wall of member 16 and which has its ends 19h folded o r bent around a cut-away section of/the memberY 8.

As illustrated in Fig. 1, the memb r 16 is in its closed position and from suchposition is adapted in any suitable manner to be biased toward and into open position as sho in Fig. 2. For thus biasing the memberl in the manner stated, there may be utilized a spring 20 which is coiled around the pind and has opposite ends thereof coasting, respectively, with the top casing wall 1 and with the interior surface of member 16.

The member 16 comprises a lip or flange 16a adapted to coact with a circular flange 5a formed on the aforesaid knob 5 whereby the rod 4 is retained in depressed position and the member 16 held in closed position.

Any suitable liquid medium, as a perfume or some medicinal agent may be suitably introduced to the casing C. For this purpose, the bottom wall 2 of said casing'Cmaybe provided with an interiorly threaded aperture adapted to receive a threaded plugflt, a gasket or the like 22, preferably, being disposed between the head of plug 21 and the adjacent surf-ace of said bottom casing wall. v

With the casing C containing a desired amount of a suitable liquid medium, the knob 5 maybe depressed from the position shown in Fig. 1. In response to su'ch depression of the knob 5,.the lip 16a of member 16 clears the flange 5a of knob 5 and said member 16, under the influence of spring 20, moves to open position carrying the member 18 from the nozzle 14a and passage 1b. Thereupon, the knob 5 may be reciprocated by thumb 'or finger action to pump air through the conduit 13, a perforation 1c being provided in the top casing wall 1, if desired, to permit entrance of air interiorly of the pump cylinder 10 each time that the plunger 4 moves downwardly.

The air streams thus intermittently produced by pump action emerge from the nozzle 13a of conduit 13 at relativelyhigh velocity and sweep past the nozzlef 14a of conduit 14 to cause the liquid medium to rise from the casing C through the conduit 14 by an aspirating action, said liquid medium, as it leaves the nozzle 14a, being atomber 18 from the nozzle 14a and the passage 1b. Accordingly, air freely enters the interior of casing C through the passage 1b, during the atomizing action, to prevent the formation of a partial vacuum in said casing.

Upon completion of the atomizing action, the knob 5 may be returned to its fully depressed position and then the member 16 may be moved to closed position whereby the lip 16a of the latter' is moved into the path of the flange 5aof knob 5. The latter may now be freed from restraint and allowed to rise, the flange 5a thereof coming into engagement with said lip 16a whereby the parts are retained in the position illustrated in Fig. 1.

An important feature of my invention-resides in the construction of the air pump. As hereinbefore described, the plug 11 is threaded into the wall ofthe pump cylinder 10 opposite the cylinder wall through which the rod 4 reciprocates. Heretofore, it has been customary to gain access to the pump cylinder through a plug threaded into the top casing wall, the pump plunger being removed entirely from the pump cylinder. How-- ever, in accordance with my invention as herein v disclosed, the plug 11 may be detached whereby access may be had to the various operating parts of the pump should it become necessary to repair the same. Moreover, various manufacturing operations, as a plating operation, is more ex-l peditiously performed when the pump construction is as herein disclosed.

While the invention has been described with respect to a certain particular preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention,` that various changes and modications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
